Console Amp ID kindly...

[RFguy]

Not being able to post pics, I'll do my best to describe it:

Stereo SE Amp, 1-8 pin octal & 1- 9 pin pre/driver tube per side, 9 pin 6 volt rectifier tube, 2 amp fuse, 3 rca inputs on separate 4 knob panel, small round sticker on amp : '416' . Output transformers(161000-183 352112) look to be 5w or better with leads coming out presumably going to the speakers. Power transformer (161000-238 352118) Multi section electrolytic can cap TVL4746 40uF 450v x3 and 50uF 50v.
I'd like to find out the model #, and a schematic if it's out there, looks like a good base for modding.

Thanks in advance, Rob :)

It would be really nice to know the types of tubes involved.
6-volt, 9-pin (!) rectifier tube: 6754? 5993? EZ80? Other?
It would be really nice to know whether the OPTs have more than one tap.
You write that this is from a console - is there a brand on the console?
Do the transformers have open coils (paper showing), or metal end-bells?

Magnavox made variations of these amps in their uncounted thousands. And they made them for many 'brands' other than their own. But so did Knight, Olsen, and a bunch of others. So more detail is needed to even get close to any sort of ID. In any case, your best bet is to draw out the schematic for yourself before looking to mod it. And note that these amps were designed to be as cheap as possible to manufacture, not necessarily a bad thing, but you need to be aware that every part and piece is being driven to, or even a little beyond, its proper design limits.
